convert tgz txz to xzm: problem with bigger files

[francois]

I often have problem to convert bigger files with the contextual right click to convert tgz txz to xzm.

As an example, my system will never make it up with a file like:
qt-4.7.0_7abde40-i486-3.txz (53.9 MB)

Do you have any advice to deal with the compression of bigger files?

Please move manually through the process to isolate where the bottleneck is.

Code: Select all

mkdir /tmp/unpack
installpkg -root qt-4.7.0_7abde40-i486-3.txz /tmp/unpack
time mksquashfs -noappend -comp gzip /tmp/unpack /tmp/module.gz
time mksquashfs -noappend /tmp/unpack /tmp/module.xzm

Probably obvious for you Francois but ... make sure you are not creating the resulting module in the same place that you are making the module from. E.g dir2xzm /tmp/unpack /tmp/unpack/module.xzm

Thanks brokenman.

This was not obvious for me. I imagine that smaller files are less affected by the process. Is this the case?

[brokenman]

Yes smaller files will process faster. In the above example however (module in same place as target) a module is being created that continually needs to be updated with it's own info. This sets up a loop that can take forever to finish.

Make sure you have enough ram in case of big files!
