I know that you can do
# semanage fcontext -C -l and send the output to a file.
This will generate lines such as
SELinux fcontext type Context
/home/mike/.cxoffice(/.*)? all files
system_u:object_r:textrel_shlib_t:s0
/home/mike/.cxoffice/dotwine/drive_c/Windows/System/SHLWAPI.DLL all
files system_u:object_r:textrel_shlib_t:s0
/home/mike/.cxoffice/dotwine/drive_c/Windows/System/ole32.dll all
files system_u:object_r:textrel_shlib_t:s0
/home/mike/.wine(/.*)? all files
system_u:object_r:textrel_shlib_t:s0
However I guess that saving this will still not allow these rules to
be written back to the new system in an automated way unless a script
is written to parse the lines and create a set of new selinux fcontext
lines that will create each local
rule with something like:
semanage fcontext -a -t textrel_shlib_t /home/mike/.cxoffice(/.*)?
with one for each original line in the output generated from the old
system before it was replaced?
If there is a cleaner way to achieve this I would like to hear about it?
You can create a local policy module and distribute that:
mything.te
policy_module(mything, 0.0.1)
mything.fc
HOME_DIR/.cxoffice/dotwine/bla/bla/mything.so --
gen_context(system_u:object_r:textrel_shlib_t, s0)
"build and install"
make -f /usr/share/selinux/devel/Makefile
semodule -i mything.pp
restorecon -R -v /home/mike/.cxoffice/dotwine
That should work
