[arch-projects] [dbscripts] [PATCH 5/5] db-move, db-abs: Simplify the abs_move_* functions

[Luke Shumaker]

From: Luke Shumaker <lukeshu at parabola.nu>

Currently, abs_move_preflight_check and abs_move_arch require the
exact pkgarch (i.e. "any" or "x86_64").  Modify them so that they take
the tarch (i.e. "x86_64") and figure out themselves if it needs to set
pkgarch=$tarch or pkgarch=any.

abs_export could probably stand to be modified to do something
similar, but it's more work to adjust its callers.

"Ignore space change" might be useful when viewing this diff.
