Below is an updated patch that makes a few changes the the latest
Sandbox Patch [1]. This requires the chcon patch [2].
Changes this patch makes:
sandbox.py
- Remove unused 'import commands'
- Uses new chcon method in libselinux [2]
- Removes the 'yum install seunshare' message
- Converts an IOError to a string for printing a warning if a file
listed in -I does not exist
sandbox.init
- Print the standard Starting/Stoping messages with the appropriate
OK/FAIL
- Abort with failure if any mounts fail
seunshare.c
- Add the MS_REC flag during mounts to perform recursive mounts
- Define the mount flags MS_PRIVATE and MS_REC if they aren't already.
The flags are only defined in the latest glibc but have been in the
kernel since 2005.
- Calls realpath(3) on tmpdir_s and homedir_s. If relative paths are
used, it wouldn't correctly detect that tmpdir is inside homedir and
change the mount order. This fixes that.

<snip>
Below is an updated patch that makes a few changes the the latest
Sandbox Patch [1]. This requires the chcon patch [2].
Changes this patch makes:
sandbox.py
- Remove unused 'import commands'
- Uses new chcon method in libselinux [2]
- Removes the 'yum install seunshare' message
- Converts an IOError to a string for printing a warning if a file
listed in -I does not exist
sandbox.init
- Print the standard Starting/Stoping messages with the appropriate
OK/FAIL
- Abort with failure if any mounts fail
seunshare.c
- Add the MS_REC flag during mounts to perform recursive mounts
- Define the mount flags MS_PRIVATE and MS_REC if they aren't already.
The flags are only defined in the latest glibc but have been in the
kernel since 2005.
- Calls realpath(3) on tmpdir_s and homedir_s. If relative paths are
used, it wouldn't correctly detect that tmpdir is inside homedir and
change the mount order. This fixes that.
