Changeset 2682 in MondoRescue for branches/2.2.9/mondo/src/common/libmondo-devices.c

Timestamp:

Sep 10, 2010, 12:13:40 AM (14 years ago)

Author:

Bruno Cornec

Message:

• mount-media function is now placed in libmondo-devices.c as used by more programs.
• Avoids calling mount_media when it's not mandatory (change the way mondorestore was working up to now but could solve some bugs reported)

File:

• branches/2.2.9/mondo/src/common/libmondo-devices.c (modified) (3 diffs)
