CentOS 7 (7.6.1810 and 7.7.1908) failing to deploy

[wings]

Problem:
Since around the time CentOS 8 was released, I have been unable to deploy CentOS 7 boxes, using either the old release which worked in the past (7.6.1810), nor the new version that came out just before CentOS 8 (7.7.1908).

I can boot the image, but it fails early in the anaconda installation program, with the error message:

ValueError: new value non-existent xfs filesystem is not valid as a default fs type

Expected outcome:
Should be able to deploy either version.

Foreman and Proxy versions:
1.22.1

Foreman and Proxy plugin versions:
Katello 3.12.3

Other relevant data:
[e.g. logs from Foreman and/or the Proxy, modified templates, commands issued, etc]
(for logs, surround with three back-ticks to get proper formatting, e.g.)

logs

Hello, this error means that the init RAM disk is corrupted. Delete it and let Foreman (Smart Proxy) to redownload it when you redeploy boot files.

Hi @lzap - literally 60 seconds ago I found your comment on https://unix.stackexchange.com/questions/446979/redhat-satellite-6-valueerror-new-value-non-existent-xfs-filesystem

where you said much the same thing

Whereabouts are the initrds stored?

[lzap]

Well, I am faster Take care.

Excellent, that did the trick!

I simply moved the contents of the /var/lib/tftpboot dir to somewhere safe, did another build and everything works again.

[root@hardhat ~]# cd /var/lib/tftpboot
[root@hardhat tftpboot]# mkdir boot-backup20191021
[root@hardhat tftpboot]# mv boot/* boot-backup20191021/

Thank you!
