Replace "sendmail" with (a link to) the script, and forward all system mails via free Mailgun acct to your chosen external address

python 40 line drop-in replacement for sendmail/postfix etc - avoid setting files when only using mail to send system notifications to fixed address
#!/usr/bin/env python3
import os
import sys
import subprocess
s = ""
s += "---- begin args ----\n"
for i in range(0,len( sys.argv )):
s+= "argv[" + str(i) + "]:" + str(sys.argv[i]) +"\n"

multi os booting with `systemd-boot` / `boot-ctl` --- case examples: LVM, LUKS with LVM, on SSD

multi os booting with systemd-boot

We set up multiple OS to be booted from a UBS SD.

Both are Ubuntu.

  • ub16 is on an LVM2 partition.
  • ub18 is on an encrypted LUKS partition with LVM2 on the inside. As it happen, the disk is SSD.

Formatting the USB SD
