Hello,
I recently completed a jhalfs build using the multilib (MLFS) branch and
encountered a failure at the very end of the process. The issue appears to
be caused by malformed parsing of DISTRIB_RELEASE, resulting in an extra
double quote being inserted into generated scripts, which causes bash to
fail with an unmatched quote error.
Build configuration:
MLFS (multilib) pulled from git
systemd init
BLFS included (also from git)
jhalfs multilib set to i686
Local modifications:
Replaced static IP configuration in Chapter 9 with DHCP setup
(systemd-networkd, per LFS/MLFS systemd book)
Added a custom package for GPU and CPU microcode firmware prior to kernel
build
These changes do not appear related, as the failure occurs during the final
cleanup stage after BLFS tool dependencies are built.
Error output:

Each instance of MLFS is prefixed with an extra double quote (""MLFS"),
which results in broken quoting and causes bash to error out.
It appears that in the MLFS branch, DISTRIB_RELEASE has been modified to
prepend "MLFS " (note the trailing space) to the version string. The space
seems to be causing improper tokenization or quoting when parsed by jhalfs
in LFS/master.sh, resulting in the extra embedded quote, and no version
identifier to be included (beyond the string MLFS).
Manually removing the leading quote (changing ""MLFS" to "MLFS") in the
generated Makefile allows the build to complete successfully.
Is this something that should be handled in jhalfs parsing logic, or should
I report this to the MLFS team?
I=E2=80=99m happy to help test a fix if needed.
Thanks,
Eric
