saves space 11/20/2003 - also retrieve /tmp/mountlist.txt if user wants 11/16 - fixed NFS path bug affecting the extractions of filelist/biggielist during selective restore 11/02 - fixed mount_cdrom() to run properly w/ nfs restores - mount_device() returns 0 if swap mount fails cos swap isn't crucial 10/17 - run_grub() uses MNT_RESTORING instead of "/mnt/RESTORING" 10/26 - cleaned up run_grub() 10/25 - fixed mount_cdrom() to run properly w/ nfs restores 10/21 - mount_device() returns 0 if swap mount fails cos swap isn't crucial 10/15 - run_grub() now uses its initiative instead of calling grub-install 10/10 - don't leave copies of filelist.full lying around, clogging up the ramdisk, there's a good fellow :-) 10/02 - added 'dvd' to the range of media types I'll understand - fixed iso->cdr problem (thanks, Stan Benoit & Fred Beondo) 09/24 - try lots of tape devs if /dev/st0 fails 09/23/2003 - first incarnation */ #include #include "../common/my-stuff.h" #include "../common/mondostructures.h" #include "../common/libmondo.h" #include "mr-externs.h" //#include "mondo-restore.h" //#include "mondo-rstr-compare-EXT.h" #include "mondo-rstr-tools.h" extern bool g_sigpipe_caught;
