Questions about mkosi log warnings

1. Are these false positives because of running in a chroot?

( 6/16) Applying kernel sysctl settings...
  Skipped: Running in chroot.
( 7/16) Creating temporary files...

Setting default ACL "u::rwx,g::rwx,g:tss:rwx,m::rwx,o::r-x" on /var/lib/tpm2-tss/system/keystore failed: Invalid argument
Setting default ACL "u::rwx,g::rwx,g:tss:rwx,m::rwx,o::r-x" on /run/tpm2-tss/eventlog failed: Invalid argument

2. What does this error mean?

‣  Generating system users
‣  Generating volatile files

‣  Applying presets…

3. Another warning I am not clear how to resolve?

‣  Applying kernel module filters
‣   Running modinfo to fetch kernel module dependencies
‣   Calculating required kernel modules and firmware
‣ nls is a dependency of cifs but is not installed, ignoring
