Operating Systems Linux Are /home partitions worth it? Post 302863793 by hergp on Tuesday 15th of October 2013 06:56:25 AM

There are several good reasons to have separate filesystems (not in any particular order):

Filling up the /home filesystem with files or using up all the inodes with tons of tiny files will not affect the operating system
In case of a filesystem damage, the loss of data is limited
I/O can be balanced over several physical devices
/home can be mounted in a way to disallow execution of s-bit programs, resulting in a higher system security
and certainly many more reasons I can't think of at the moment :-)

But of course there are drawbacks

free space is distributed over several filesystems resulting in more unused space. One filesystem can not borrow space from another (in most cases)
on specialized servers, like a DNS server, with no users but the admins, the overhead is unneccesary

Conclusion: in my opinion, the advantages of separate filesystems outweigh the disadvantages by far in most cases. This is valid for all kinds of *ix operating systems.

virtual-filesystems

virtual-filesystems(7)					 Miscellaneous Information Manual				    virtual-filesystems(7)

NAME

       virtual-filesystems - event signalling that virtual filesystems have been mounted

SYNOPSIS

       virtual-filesystems [ENV]...

DESCRIPTION

       The  virtual-filesystems  event	is  generated  by  the mountall(8) daemon after it has mounted all virtual filesystems listed in fstab(5).
       mountall(8) emits this event as an informational signal, services and tasks started or stopped by this event will do so	in  parallel  with
       other activity.

       This event is typically used by services that must be started in order to mount other filesystems.  When this event occurs, common filesys-
       tems such as /usr may not be mounted.  For most normal services the filesystem(7) event is sufficient.

EXAMPLE

       A service that wishes to be running once virtual filesystems are mounted might use:

	      start on virtual-filesystems

SEE ALSO

       mounting(7) mounted(7) local-filesystems(7) remote-filesystems(7) all-swaps(7) filesystem(7)
