Subject: Add new file copy mode for recovery patition - MVWITHLIBS
X-Git-Tag: submit/tizen/20170823.081423~5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dbf7a9fd63ab1dc60df67df6b94e8d73bade2f0e;p=platform%2Fcore%2Fsystem%2Finitrd-recovery.git

Add new file copy mode for recovery patition - MVWITHLIBS

To reduce rootfs size, we need to erase some redundant files.
Especially, files used in just recovery partition should be removed from rootfs.

Until now, the existing file copy mode of current recovery partition creation support followings.
1) Symlink creation in just recovery partition
2) Copy binary with related lib (related lib is copied)
3) Copy just the binary without related lib
               :

However, there are no copy mode - Move binary with related lib (related lib is copied)
If recovery partition has such copy mode, some binary can be removed from rootfs.

This patch supports such requirement, and modify existing scripts
