### Error in refractasnapshot-gui_9.0.6-1

by dzz » Fri Oct 26, 2012 3:53 pm

First test failed with (snip from log)

Code: Select all
  `mksquashfs: invalid option
  SYNTAX:mksquashfs source1 source2 ... dest [options] [-e list of exclude
  dirs/files]`

Everything was fine after changing /usr/bin/refractasnapshot-gui (line 332) from:

Code: Select all
  `mksquashfs myfs/ iso/live/filesystem.squashfs "$mksq_opt" \`

to

Code: Select all
  `mksquashfs myfs/ iso/live/filesystem.squashfs ${mksq_opt} \`

BTW Maybe it is better to use xz as option not default in snapshot. Standard squeeze mksquashfs chokes on the -comp option. It is good to have newer versions work in squeeze as well as wheezy/sid. In all cases default compression mode for mksquashfs, i.e. no options at all, is gzip
Example for refractasnapshot.conf (should work with $mksq_opt not set at all):

Code: Select all
  `# uncomment below to use xz compression (*not* for standard Squeeze squashfs-tools)
  #mksq_opt="-comp xz"`

It is possible to use xz in squeeze, I will write elsewhere about that
The isolinux splash looks good

Tested here 9.0.6-2 in both modes, xz and (default) gzip
Successful snapshot for each !
The "test" root filesystem here has changed, it keeps getting a little larger. I keep adding more just because... it can still be <700MB
xz : 743MB
gzip : 652MB
This test is not from original refracta but squeeze with TDE, LXDE, latest backport kernel, latest backport squashfs-tools. Good, (although refracta is also good) snapshot is not restricted to Refracta only. Not yet tried this with wheezy/sid due to (gtk3-related) stomache issues
Not even tried to boot them yet but would be very surprised if they don't...
(previous experience): Xz compression is much slower... decompression makes little significant difference
Nice isolinux splash

Yea I stopped using xz as it was soooo slow when I made a snapshot.
I could swear I recall reading on the debian-live list or somewhere that xz would be default with wheezy and up.

Had a 'funny' hang at post-unetbootin boot menu around early text info of USB flash mem-cache write through (IIRC). Squashfs at 2.6GB. Refracta Snapshot log reported possible issue with some BIOS not booting correctly.
All is good though. FWIW, switched to standard ISO and XZ compression in etc refractasbapshot.conf. Image now around 2.4GB, boots as expected to full desktop (that's FPS,Oolite,LibreOffice,Soundfont libraries, tonnes of great audio, graphic and video apps).
