It would be nice to be able to remount devices

[jkozak]

For example to change read-only status.

but things like:

udevil mount -oremount,ro /media/blah

don't work

[IgnorantGuru]

udevil does handle remount (except for mounted ISO files, ftp, sshfs). Being an suid program it is very particular about the usage. You need a space after -o and it seems you need to specify the device, not the mount point.

udevil mount /dev/sdc1
udevil mount -o remount,ro /dev/sdc1
udevil umount /dev/sdc1

Not being able to specify the mount point may be a bug - not sure if that limitation was intentional or not. The error it gives seems to be wrong.
