fstab extended partitions
I was cleaning up my computer this morning, and I decided to move my programming projects to another partition that I wouldn't wipe out in the event of a reinstall. This partition happens to be a logical drive on an extended partition.
I've found I cannot execute any scripts from that drive (you may recall my previous troubles with nvidia) without explicit declaration of the interpreter in the command line (eg. perl stats.pl).
Using the mount command
Code:
$mount
/dev/hda2 on / type reiserfs (rw)
proc on /proc type proc (rw)
/dev/hda4 on /home type reiserfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/hda5 on /media type reiserfs (rw,noexec,nosuid,nodev)
/dev/hda6 on /asdf type reiserfs (rw,noexec,nosuid,nodev)
/dev/hdc on /mnt/cdrom type iso9660 (ro,nosuid,nodev)
/asdf/iso/slack/slackware-10.0-install-d1.iso on /mnt/slack1 type iso9660 (ro,nosuid,nodev,loop=/dev/loop0)
/asdf/iso/slack/slackware-10.0-install-d2.iso on /mnt/slack2 type iso9660 (ro,nosuid,nodev,loop=/dev/loop1)
/asdf/iso/slack/slackware-10.0-source-d3.iso on /mnt/slack3 type iso9660 (ro,nosuid,nodev,loop=/dev/loop2)
/asdf/iso/slack/slackware-10.0-source-d4.iso on /mnt/slack4 type iso9660 (ro,nosuid,nodev,loop=/dev/loop3)
I find that /asdf has the noexec option engaged.
So I've been mucking about with fstab and have been failing to see why I should be able to execute off of my /home partition but not my /asdf.
Code:
/dev/hda1 swap swap defaults 0 0
/dev/hda2 / reiserfs defaults 1 1
/dev/hda4 /home reiserfs defaults 1 2
/dev/hda5 /media reiserfs defaults,users,rw 1 2
/dev/hda6 /asdf reiserfs defaults,users,rw 1 2
/dev/hdc /mnt/cdrom iso9660 auto,owner,ro 0 0
/usr/iso/slack1 /mnt/slack1 iso9660 loop,auto,owner,ro 0 0
/usr/iso/slack2 /mnt/slack2 iso9660 loop,auto,owner,ro 0 0
/usr/iso/slack3 /mnt/slack3 iso9660 loop,auto,owner,ro 0 0
/usr/iso/slack4 /mnt/slack4 iso9660 loop,auto,owner,ro 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0
/dev/sda1 /mnt/usb1 vfat noauto,users,rw 0 0
/dev/sdb1 /mnt/usb2 vfat noauto,users,rw 0 0
/dev/sdc1 /mnt/usb3 vfat noauto,users,rw 0 0
/dev/sdd1 /mnt/usb4 vfat noauto,users,rw 0 0
It occurred to me... perhaps logical drives must be mounted noexec? That would explain my predicament. Can anyone confirm this suspicion? Perhaps even suggest clever ways of getting around it (can't ln -s the programs to /usr/bin, I've tried).
