Loop device is read only
I can't seem to write to an image I downloaded and mounted as a loop
# ls -l /opt | grep floppy
drwxr-xr-x 2 root root 4096 Jun 18 10:08 floppy
# mount -o loop fdbasecd.iso /opt/floppy/
# grep loop /etc/mtab
/dev/loop0 /opt/floppy iso9660 rw 0 0
# mount | grep loop
/dev/loop0 on /opt/floppy type iso9660 (rw)
# touch /opt/floppy/test
touch: cannot touch `/opt/floppy/test': Read-only file system
# ls -l /opt
dr-xr-xr-x 4 root root 2048 Sep 4 2006 floppy
I don't think it's the ISO... I downloaded it here:
What could cause my permission to go from 755 to 555?
How can I put some more data into this ISO?
or alternatively... my need is to get a Supermicro BIOS update into a
bootable DOS diskette image or cdrom image that I will then mount as
virtual media with Supermicro's IPMIView tool. If there's a better way,
please suggest. Thanks!
