# ctrlx_prep_mount_nfs4_files.bash - collect Debian files for mount.nfs4
# so that they work on a CTRL/X ARM64 machine
#
# Written by Roland Mainz <roland.mainz@rovema.de>
#

#
# Usage:
# 1. prep tarball with ARM64 binaries using this script
# 2. copy resulting 'ctrlx_mount_nfs4_files.tar.bz2' to target machine
# 3. ssh into target machine
# 4. execute these commands ('$' is user prompt, '#' is root prompt)
#
# $ sudo bash
# # cp 'ctrlx_mount_nfs4_files.tar.bz2' <path-to-root-dir-of-rexroth-deviceadmin-snap>/.
# # snap run --shell rexroth-deviceadmin.web
# # tar --no-same-owner -xf ctrlx_mount_nfs4_files.tar.bz2
# # $ (LD_LIBRARY_PATH=$PWD/ctrlx_files/lib/aarch64-linux-gnu ctrlx_files/sbin/mount.nfs 10.49.20.131:/net_tmpfs /mnt)
# # ls -l /mnt
# total 4
# -rw-r--r-- 1 4294967294 4294967294 48 Nov 22 16:42 secret.txt
