 simple /bin/mount |
|
Without words ,
still has to be tested for
Windows filesystems ,
/etc/eventmanager settings ,
removable devices.
Main goal for me is to mount /dev/sdaX using the cli without need for mountpoint or /etc/fstab.

Edit1 : fix for ntfs mount options not understood by ntfs-3g
Edit2 : add support for floppy, fix probably incorrect mmc* devices handling ( have no mmc* device, so can not test )
Edit 3 : use mount-FULL -t ntfs-3g instead of ntfs-3g directly
Edit 4 : typo in "case $DEVNAME in" line ( was DEVAME ) ; fixed removable srX devices ( was grep "^${device//[[:digit:]]/}|" [..] now is grep -m1 "^${device:0:8}|" ) in call for probedisk2 line .
Edit 5 : Added check for "$DRV_CATEGORY" before icon_mounted_func [..] in case device is some pseudo device ( loop, ram )

Tested succesfully on removable device.
Unmounted by click on x at desktop drive icon.
Windoofs not available here. 
| Code: | # /sbin/mount /dev/sda2
# /bin/mount /dev/sda2
mount: can't find /dev/sda2 in /etc/fstab or /etc/mtab
# /sbin/mount /dev/sdb2
# |
(I had it in /sbin/bin thus not overwriting /bin/mount.)

Recognized it also here .
Fix would be to screen out the mount options like
| Code: | [ "$NTFSMOUNT" ] && {
for sp in ${P[@]}
do
case $sp in
/*|-o) NTFS3G_OPTS="$NTFS3G_OPTS $sp" ;;
-*|ntfs) : ;;
*) NTFS3G_OPTS="$NTFS3G_OPTS $sp" ;;
esac
done
ntfs-3g ${NTFS3G_OPTS} && RETVAL=$? || {
mount-FULL ${P[@]} && { RETVAL=$? ; NTFSRO=YES ; } || RETVAL=$? ; } ; } |
Am adding this to the script above.
Edit : done

Reading the manual page there are two ways to mount ntfs read -write :
| man ntfs-3g wrote: | SYNOPSIS
ntfs‐3g volume mount_point [‐o option[,...]]
mount −t ntfs‐3g volume mount_point [‐o option[,...]]
|
The latter works for me too :
First needs to set
[ "${P[$c]}" = ntfs ] && P[$c]='ntfs-3g'
in the ARGV formatting part
and
ntfs-3g) NTFSMOUNT=YES;;
in the case ntfs) vfat) part
and
| Code: | [ "$NTFSMOUNT" ] && {
mount-FULL ${P[@]} && RETVAL=$? || {
mount-FULL ${*} && { RETVAL=$? ; NTFSRO=YES ; } || RETVAL=$? ; } ; }
|
and looks better.

Second style :

Edit1 : forgot and added $RETVAL to one exit: /usr/sbin/filemnt was saying error but mount was successful (debian squeeze pup )
Edit1 : added *) exit [..] to case $DEVNAME in line .

/etc/mtab |
|
While experimenting with the line
[ -L /etc/mtab ] || ln -sf /proc/mounts /etc/mtab
if that is needed nowadays anymore (/etc/mtab),
it turned out that mount seems not to need it, but /bin/df-FULL .
busybox df does not need /etc/mtab on (slacko-5.3.1).
/bin/df is a wrapper script that does assign
DF="busybox df"
[ "`which df-FULL`" != "" ] && DF="df-FULL"
which could look like
| Code: | DF="busybox df"
[ "`which df-FULL`" != "" ] && { DF="df-FULL" ; [ -L /etc/mtab ] || ln -sf /proc/mounts /etc/mtab ; } |
But since df is called many times by the (old)pup_event_frontend_d and freememapplet[_tray],
it would add a little to the load average .
IMHO the link /etc/mtab -> /proc/mounts
should be created by /etc/rc.d/rc.sysinit after /proc is mounted ,
so it could be omitted in any userspace scripts .
Risky , probably if something removes /etc/mtab , but I cannot think of anything else but the user, and that could remove also any other important files in /etc .
