...tem.* namespace which the kernel handles specially, but there are also a bunch of bugs associated with extended attributes & guestmount and maybe this is one of them. It should be possible to read and set the attributes through the API (eg. using guestfish). See the APIs guestfs_lsetxattr and guestfs_lgetxattr and related.

This version doesn't crash or cause hung processes or stuck mountpoints, so that's an improvement. Rich.

This patch is just for review. It enables FUSE support in the API via two new calls, 'guestfs_mount_local' and 'guestfs_umount_local'. FUSE turns out to be very easy to deadlock (necessitating that the machine be rebooted). Running the test from the third patch is usually an effective way to demonstrate this. However I have not yet managed to produce a simple reproducer that

This changes the proposed API slightly. Previously 'mount-local' generating a 'mounted' event when the filesystem was ready, and from the 'mounted' event you had to effectively do a fork. Now, 'mount-local' just initializes the mountpoint and you have to call 'mount-local-run' to enter the FUSE main loop. Between these calls you can do a fork or whatever

...API changes "guestfs_set_selinux", "guestfs_get_selinux", "guestfs_setcon", "guestfs_getcon" and "guestfs_llz" have been deprecated. Use the new API "guestfs_selinux_relabel" to relabel filesystems. Use "guestfs_lgetxattrs" to list the "security.selinux" extended attributes of existing files. "guestfs_vfs_minimum_size" can now be used on dirty filesystems (Maxim Perevedentsev). "guestfs_ll" now works on paths which contain absolute symlinks (Pino...
