# Utilities diff, mv, rm, rmdir are necessary to assist with package upgrading
# after https://github.com/termux/termux-packages/issues/4070.
#
# Other utilities (like crond/crontab) are useful but not available
# as standalone package in Termux.
#
# Few notes:
#
# * runsv, runsvdir, sv - for things like in https://github.com/termux/termux-packages/pull/3460.
# * tcpsvd - required for ftpd applet.
# * vi - replaced by vim, but it still good to have basic text editor in bootstrap.
# * which - replaced by debianutils, but still good to have in bootstrap.
