Entware-ng installation error

[Marko Polo]

I decided to install Entware after my unsuccessful experience with Optware, but have problems here too.
I followed the manual and here is my script output:

What should I do?
It says mkdir: can't create directory '/opt': File exists but it does NOT exist. Neither it's added to PATH, nor to target partition. Here is listing from partition I am installing Entware to:

drwxrwxrwx   11 polo root          4096 Jul 19 21:26 Downloads
drwxrwxrwx    2 polo root          4096 Jul 20 09:46 entware
-rw-rw-rw-    1 polo root           363 Jul 20 09:46 jffs_scripts_backup_2017-07-20_09-46.tgz

Your /jffs/ partition seems nonexistent or corrupted. Consider setting the reformatting tick in Administration/System and reboot router to do so.
Make backups of files in there first.

Also, remnants of the Optware install appear to be present:

rm -f /tmp/opt
rm -f /opt

If you had Download Master installed at one time, there's more:

nvram set apps_mounted_path=
nvram set apps_dev=
nvram set apps_state_autorun=
nvram set apps_state_enable=
nvram set apps_state_install=
nvram set apps_state_switch=
nvram commit

Thanks, router reboot helped, and Entware was installed. Could you please clarify this thing I asked in the other thread:

And how to re-fetch new PATH value from profile.add without reboot?

Is it possible at all?
Also, it's interesting do I need paths like:

/mmc/bin
/mmc/sbin
/mmc/usr/bin
/mmc/usr/sbin

in my $PATH? These dirs are non-existent on my device.

By running $HOME/profile.add if that's where the file is.
You need to log out and back in with your SSH client for this to take effect.

Also, it's interesting do I need paths like:
/mmc/*

I have no idea what this is used for, mine is empty.
I suppose if Download manager or Optware is installed this is added to the $PATH when needed.

I've have the /mmc directory on the routers I have with DD-WRT firmware. But not the subdirectories. The /mmc directories and subdirectories are also part of the default $PATH variable.

/bin:/usr/bin:/sbin:/usr/sbin:/jffs/sbin:/jffs/bin:/jffs/usr/sbin:/jffs/usr/bin:/mmc/sbin:/mmc/bin:/mmc/usr/sbin:/mmc/usr/bin:/opt/sbin:/opt/bin:/opt/usr/sbin:/opt/usr/bin

Looking at the DD-WRT wiki, it appears the /mmc directories is an SD Card replacement alternative for /jffs that is an option for Optware.

Probably okay to remove those directories and files.
