My wipefs has no --force option, as a result mke2fs command in guestfish fails. Looks like 72dd398679cd0bb803daf306d12558369615ba70 needs an adjustment to make use of do_wipefs? Also str_wipefs is not used in that file. Olaf

Also daemon/zero.c has a wipefs_has_force_option function. It seems like it would be better if this function was also used in wipe_device_before_mkfs (in the same file). But yes, it's definitely a bug if wipefs is causing mke2fs to fail. How...

Hi Rich: This is a alternative patch, if you like the api name called wipefs ;-P Thanks -Wanlong Gao Wanlong Gao (2): NEW API: add a new api wipefs virt-format: erase the filesystem signatures before erase partitions TODO | 2 -- daemon/zero.c | 17 +++++++++++++++++ format/format.c | 19 ++++---------------

This is a simpler patch that removes GUESTFSD_EXT_CMD completely.

Replace GUESTFSD_EXT_CMD with a command line option ‘./guestfsd --print-external-commands’
