Not a good idea...Unless you like fighting with funky issues....
That said in there (/var/adm/sw) you will find all the patches installed (and obsoleted, and uninstalled etc...) You may gain space by intellingently doing some cleanup, beware of the risk of not being able to "rollback" removed patches afterward... but very first superseeded patchs are of little risk...
What about /var/adm/syslog? what size are the logs there?
I trim them regularly ( customized by me though - important info in beginning syslog (at boot time) is always kept till next reboot...)
...
There are logs in /var/stm you can clean also and save 10-400 MB...
I have an old 10.20 that makes me sweat regularly (vital old legacy stuff nobody wanted to port : forms 3 with oracle 7.2.3...)
I only have this unique volume group vg00 in mirror on old SCSI 9GB (all space saving is important...) with all on it.
When I forget to look (thanks for reminding me Hehe...) the system crashes... and this box is not on site but in the countryside (with snow lately and Im on motorcycle...)
I just zero activity_log periodically, So Do it today:
Look at how fast its growing though:
approx 12k/min

Hi Everyone,
I think I've filled up one of the partitions on my drive. I suspect that one of the applications I've been running has been spitting out junk files to this partition - most of which can be deleted. The problem is that I have no idea how to go look at what's on that partition and... (2 Replies)

I am currently running DesktopBSD as a live-CD and need to have a large /var partition because it is currently too small. I have a USB stick which is BSD formatted, and would like to have the /var partition moved over to it. How can this be done? Could I for instance use a symlink? (1 Reply)

This is my first time working with ZFS on Solaris 10. I am trying to set up /var in a separate partition from /.
During the installation, I came across the ZFS settings where I selected disks 0 and 1 to be mirrored with ZFS. Next was the option to have /var and / on separate datasets.

pivot_root
PIVOT_ROOT(8) Maintenance Commands PIVOT_ROOT(8)NAME
pivot_root - change the root file system
SYNOPSIS
pivot_root new_root put_old
DESCRIPTION
pivot_root moves the root file system of the current process to the directory put_old and makes new_root the new root file system. Since
pivot_root(8) simply calls pivot_root(2), we refer to the man page of the latter for further details.
Note that, depending on the implementation of pivot_root, root and cwd of the caller may or may not change. The following is a sequence for
invoking pivot_root that works in either case, assuming that pivot_root and chroot are in the current PATH:
cd new_root
pivot_root . put_old
exec chroot . command
Note that chroot must be available under the old root and under the new root, because pivot_root may or may not have implicitly changed the
root directory of the shell.
Note that exec chroot changes the running executable, which is necessary if the old root directory should be unmounted afterwards. Also
note that standard input, output, and error may still point to a device on the old root file system, keeping it busy. They can easily be
changed when invoking chroot (see below; note the absence of leading slashes to make it work whether pivot_root has changed the shell's
root or not).
EXAMPLES
Change the root file system to /dev/hda1 from an interactive shell:
mount /dev/hda1 /new-root
cd /new-root
pivot_root . old-root
exec chroot . sh <dev/console >dev/console 2>&1
umount /old-root
Mount the new root file system over NFS from 10.0.0.1:/my_root and run init:
ifconfig lo 127.0.0.1 up # for portmap
# configure Ethernet or such
portmap # for lockd (implicitly started by mount)
mount -o ro 10.0.0.1:/my_root /mnt
killall portmap # portmap keeps old root busy
cd /mnt
pivot_root . old_root
exec chroot . sh -c 'umount /old_root; exec /sbin/init'
<dev/console >dev/console 2>&1
