Operating Systems Solaris My /etc/mnttab file is showing ro permission for /usr Post 302498385 by jlliagre on Monday 21st of February 2011 07:47:50 AM

For some reason, your /usr file system is on a iso image (likely a cd or dvd). You obviously cannot remove files from it.

NAME
mkcd - create bootable Solaris ISO image SYNOPSIS
/usr/bin/mkcd -v [-l label] media-root iso DESCRIPTION
The mkcd utility takes media-root (the root of an on-disk Solaris install media) as input and creates a bootable Solaris ISO image in the file iso, using mkisofs(8). The file can then be burned onto a CD/DVD with utilities such as cdrw(1) or cdrecord(1). (Neither mkisofs(8) nor cdrecord(1) are SunOS man pages.) Caution - The directory tree media-root must contain the file boot/grub/stage2_eltorito, which will be written to the media boot sectors. This file will be modified with some boot information, thus it must be writable. If necessary, first save a copy prior to running this utility. OPTIONS
The following options are supported: -l label Sets label as the label/volume name of the ISO image. -v Verbose. Multiple -v options increase verbosity. OPERANDS
The following operands are supported: media-root Top-level directory of an on-disk Solaris install media. iso Name of the output file which will contain the resulting ISO image. EXAMPLES
Example 1 Creating an ISO Image and Burning a CD/DVD The following commands create an ISO image from the content of s10u1 and burn the image to a CD/DVD. # /usr/bin/mkcd s10u1 s10u1.iso # /usr/bin/cdrw -i s10u1.iso ATTRIBUTES
