For the benefit of lualoader, add all bootenvs to environment when init_zfs_bootenv is invoked. All of the boot environment logic can then be implemented in pure lua, rather than going back and forth with C to implement paging. This stores all boot environments in bootenvs[idx] and the final count of bootenvs in bootenvs_count. While here, make a copy of currdev for init_zfs_bootenv since it will be modifying it and the caller may not necessarily want that. Some of the logic was shifted around so that the 'currdev' pointer remains at the beginning of the string and 'beroot' is moved around as needed to modify it or ultimately store it in zfs_be_root. The original zfs_bootenv that this was copied from will be able to go away only if/when forth eventually goes away. Tested with: lualoader (and local changes to add boot env. support) Tested with: forth Reviewed by: cem (earlier version), imp Differential Revision: https://reviews.freebsd.org/D14435 |
