Photon 3.0 r2 pxe boot install fail repo= not handled properly

Photon 3.0 pxe boot installs with repo=http://192.168.1.1/RPMS/ fine
./installer/iso_config.py detects repo= in the kernel args and sets rpm_path accordingly

In Photon 3.0 Rev 2 pxe boot installs fail, repo= is no longer correctly handled

in ./installer/isoInstaller.py repo_path = options.repo_path which may not be null

later "if not repo_path: repo_path = arg[len("repo="):]

perhaps the "if not repo_path:" at line 32 should be removed?

@kl1059, not sure what you mean. As it stands, the repo path passed to isoInstaller.py takes precedence over that sent over kernel command line.

[YustasSwamp]

In Photon 3.0 Rev 2 we introduced command line parameter '--repo-path' for isoInstaller.py.
And it has higher priority over kernel 'repo=' parameter.

If '--repo-path' is not set, then kernel's 'repo=' will be used.

What kind of installation failure are you facing? Can you attach screenshot or /var/log/installer.log file, please?

PXE boot install of photon-3.0 succeeds

PXE boot install of photon-3.0 rev 2 fails just after answering Yes to the
partitioning step. repo= is ignored. the installer tries to mount the
CD/DVD device and this fails.

From the log file I see 'repo' was set to /mnt/cdrom/RPMS. Which seems incorrect.
Looks like it was forced to that value in /bin/bootphotoninstaller script. Hmm regression.

At any time during the installation, press Ctrl+C, or pick "Cancel" at Welcome screen to get to shell,
and then:

1. Modify this script by running:
   sed -i 's@ -r /mnt/cdrom/RPMS@@' /bin/bootphotoninstaller
2. Run installer again:
   /bin/bootphotoninstaller

the change to /bin/bootphotoninstaller works! we will make a new initrd with this change. thanks.

this did, however, raise another issue which would only be seen by a pxe boot with an http repo.

the mode of the rpm files on the 3.0 CD are 644.

most of the rpm files on the 3.0 rev 2 CD have the execute bit lit and some http servers do not like to serve executeable files if they are not explicity declared as cgi.

it is a minor nitpick and we can change the mode of files on the http server easily.

Glad that it worked. We are fixing it right now.
Thank you for pointing to file permissions issue, will address it as well.
