1. The itch was there from a long time...yesterday, satisfied it
2. Jun26 iso from bear alienbase failed to download after 6 attempts. Downloaded Jun23 iso from princeton edu mirror..speed never fell below 1mbps
3. Installed and upgraded

4. Kernel upgrade takes a long time....for around 6 minutes, it keeps on deleting old files....Desktop PC...UPS has failed..recession...cant buy another one..was praying to god that power does not interrupt.
5. Texlive--package--files deleted for 8 min...took 6min to install...

Finally, I got fed-up and decided to remove things I do not need. I am not a programmer / developer, just an end user with technical (Electronics) background, does not like MS$ products
1. Removed Rust, Ruby...I want to remove golang also. This should not hinder the normal working of this PC, right? I have removed thunderbird, seamonkey and some emulator for emacs, nano. When emacs, nano itself are installed, why we need these emulators?
(I use LibreOffice, VLC, heavily, but not included in the 3.3GB ISO. DVD can take up to 4.7GB. Wonder why this is left out.
I hope to reduce the burden on upgrades, by keeping only what is needed

My query.
1. Pl. inform if this install will be adversely affected as a result of above actions
2. Pl. inform what other things I may safely remove, to make this lightweight. KDE not at all installed

Removing dev packages won't help you much to minimize the time needed for removing old packages, download and installation of new ones. To check, have a look at this ChangeLog. But doing so will make you risk to break your system, as Slackware does not provide automatic dependencies checking.

As you seem to have a slow internet connection, better maintain a local mirror of the Slackware-current using rsync, possibly setting up a cron job to update it daily, and do the system updates getting the packages from this local mirror.

Also, be aware that using current you will need to pay attention to the ChangeLog, to apply the updates (upgrades, additions and removals) in the proper order to avoid breakages.

If you not interested to invest your time in such tasks, my advice is simple: stay with 14.2, as for your usage using current won't bring you much. Unless you maintain current alongside 14.2 out of curiosity or as a learning occasion, indeed.

Anyway, good luck.

Thanks Didier, for your comments
Since Slackware 15 does not appear on the horizon in some months to come, I was feeling frustrated....also seeing the comments here on the forum

Correct...Current is not aiding me in any way, only daily updates that too needs my care...
Slackware14.2 has been rock solid...Ok...will wait for Slackware15

Earlier, on this HDD, on which Slackware-current was installed, I had installed Haiku to experiment...FreeBSD drivers realtekwifi RTL8192EE not supported...so
Now, I am curious about AdelieLinux..will try that on this HDD....Actually waiting for Dragora3 to be released...in the meanwhile I will check out AdelieLinux
Thanks again..
